hopper is arranged on each side of the center line of the car, each hopper havingffone1 of the dump doors referred=` to in one ofl itsv walls and one of the long sloping members referred to as'the` other of its walls. In other words, the walls of said hoppers are formed by the transversely extending` A-y shaped. portion in the middle of the' cary andl the longy sloping members at. the. endsl of' :For the purpose erplai'ni-ngV the inve'n/ tion, a: dumpear has eillustratedfhafvingf.; sides 10,; ends and a'- floor; the structure of? which floorJ differson.- ppositesides f* the' holsters 1:2.-- Theffloorfcenstruc'tionf te'rmediate'TV of theholsters* 12; includ n transversely arranged A-shaped porti-omgthel The. present:l invention relates to dump' arranged wall'kgbei-ng' formedigby kthe; slep-l ing;I4 member 1 7 which extends downwardly toward-the transverse' center line' of they car,f said sloping; member in the car show n.- exstantiallyl over theBAK bolster. 12v The; eXit opening ai;v they lowerend?` ofthe memberY 17 is normally closed by the transversely; arf-V ranged dump door 14, which when'fclosedr forms@ a tightifsea-l with# the lower` edge of mem-ber 17.y Itqwilllbeunderstood that'thef dump doors 121 forming;portions?v `of" the:y transverse central Aeshapedi-structure swing' r inwardly towar'dfY each' otherwhen moved` into open `position ,and outwardly away: fromv eachpther' when! moved into. closed position.` These; transverse *durrip doors 14A may be operated by 'any' preferred operating mechenismflit 1J i It will bei understood. that while-` I; have* heredescribed a well-known formy of hopper"- arrangement* for dump,"` carsthis" arranges, mentV `betw` eien theltrucks forms.- no l part* ofi my present linvention asfether` hopper and dumping-' arrangements may be' `snbsstituted therefor.`l` I have, howeverf showny a; car in which the dumping mechanism between/the trucks is-general-lywat a?? lowerslpleveljpthan the; dumpingfmechanism over the trucksJ as` willibe described: e .y Y

The licor portions over wthetruoks atv each g endl of the car preferably take VVthejwiform of: Hoppers 19 f the! lover. pertoe .ef e911 0f@ Whichze formed by a herizentelly arranged, dem' 20s/ Wheh vhorantalv ertefised .OlOOrSli y 20 are mounted to swingabutf the longitu# y tending,from,` a transverse" linelyingf sub# art.

dinally placed rods 21-21 which are supported from the center sill construction 22. The center sill construction 22 has the shedding frame members 2323, which with the doors V20-20 form the bottoms of the hoppers 19-19, said doors extending substantially to the side edges of the car. T he shedding frame members 23-'23 are arranged in a sloping position extending downwardly from the longitudinal center line of the car toward the ysides of said car. By thus having the'doors 2O located below the top of the center sill structure, the carry-l ing capacity of the car, and especially that of the end portions o the car, is greatly in-lcreased and at the same time the car is selfcleaning. 7 Y

The exit flow of dumpable material in each half of the car is'divided at the topy of the sloping member 17, part of the material sliding longitudinally toward the transverse center line of the car and the remaining part flowing downwardly and sideways from the longitudinal center line of the car. Preferably the top of sloping member 17 will be above the center sill construction 22 and above the bottoms of hoppers 19-19. The car is entirely self-cleaning, whereby the labor of completely emptying the car is materially reduced.

One embodiment of the present invention has been described in detail. Many modications will occur to those skilled in the y It is intended iny this patent to cover all such modifications'that fall Within the scope of the invention as defined b-y the appended claims.
